Singer Keri Hilson has sparked fears for her health after vomiting and fainting on a flight on Friday.

The “Knock You Down” hit maker has been in China this week, but Hilson’s hectic schedule has taken its toll on the star.

The 29-year-old took to her Twitter page on Friday to reveal she was taken ill on an airplane as she left the country, and she blames her lack of sleep for the health scare.

In a post, she writes, “Sure hope my day gets better cuz (because) this morning I’m having so far… I fainted on my flight. then I threw up. I’m fine now, I just need real rest… haven’t had more than 3.5hrs of sleep in 48hrs.”

Hilson, who is heading back to her native U.S., admits she began to feel better after coming round but was so distracted by her sickness she left several personal belongings on the flight.

Hilson was embroiled in the scuffle as the security guards pulled the man away and she has spoken out against his treatment.

In a series of posts on Twitter, she writes, “To the guy who ran on stage & stole a kiss, I love you too. Didn’t appreciate how u (you) were handled. But next time, enjoy from the audience… I just learned that dude jumped from the 2nd story (sic) balcony for the task… OK, so maybe he was a lil (little) crazy! Just jokes. I love my fans…”

She later added, “I hear it looks like I got hit during the fan incident? Oh please. Not a scratch. But I felt kinda bad for dude…”

A Keri Hilson fan was punched in the face and dragged off a stage by three bodyguards and the R&B star’s drummer after attempting to kiss her at a concert. The “Knock You Down” hitmaker was performing …

As he reaches his arms around her and leans in for a kiss, a security guard races from the wings and drags the man away, but Hilson is pulled along with him.

Two more bouncers move in and one of them punches the unidentified man in the face before Hilson’s drummer leaps from behind his kit and helps them drag the man off the stage. Hilson was shaken but apparently unharmed, and managed to complete her performance.

Online reports suggest the incident took place at a venue in Paris, France, although Hilson’s official list of dates on her current world tour does not include a gig in the city.

Keri Hilson has apologized after sparking outrage by posting a picture online of her partying with an Amy Winehouse lookalike just hours before the British star’s funeral on Tuesday.

The “Rehab” hitmaker was found dead at her north London home on Saturday, and a string of stars, including Lady Gaga, Russell Brand and Adele, have all paid moving tributes ahead of Tuesday’s private funeral.

But Hilson attracted a slew of criticism just hours before the service by uploading a photo of her partying with a Winehouse lookalike and joking that the Brit has been “resurrected.”

On her Twitter page, she posts a link to the image with the message: “*gasp* Amy Winehouse resurrected to party w/ (with) me!!! (seriously, uncanny resemblance).”

Her comments and photo were met with an angry outcry from her followers and within an hour, Hilson took to the site again to apologize to fans offended by the post.

She writes, “Come on, I mean no harm. All due respect. But really the resemblance freaked me out. This was simply the best tribute ever. RIP AMY WINEHOUSE… I apologize 2 anyone who might’ve taken it the wrong way. As a fan, I thought it was cool that she dressed up to honor Amy. I had no ill intent, but I understand how it appears insensitive… my bad twitterville. For real.”

R&B star Keri Hilson was left red-faced on a recent trip to London after a hotel room mix-up led her to walk in on Avril Lavigne while the pop star was relaxing in her suite.

The “Knock You Down” hitmaker checked into The May Fair Hotel, but didn’t realize her room had been doubled-booked – and she had no idea Lavigne was in the suite when she entered with her 10-strong entourage.

Hilson reveals her security guard went in first and Lavigne was given a serious fright when she spotted an unknown man in her room.

Hilson tells Britain’s Daily Mirror, “My bodyguard went into the bedroom and saw a girl sitting on a chair who almost jumped out of her skin. Her magazines were all laid out on the bed. I thought, ‘Wow, this is a good service if it comes with the hotel!’.

“When I was told it was actually Avril Lavigne’s room, I said, ‘Oh, my God!'”
